Game loop tick count

Hi there, the most common way to implement game loop around internet is const int FPS = 25; const int FrameDuration = 1000 / FPS; const int MaxFrameSkip = 5; long nextFrameTime = time(); float interpolation; int loops; while( isGameRunning ) { loops = 0; while( time() > nextFrameTime && loops < MaxFrameSkip ) { updateGameState(); nextFrameTime += FrameDuration; loops++; } interpolation = .....; render(interpolation); } The author says that updateGameState() calls 25 times per second, now less, no more. In my mind this mean that while should run 25 times. Am i wrong? According to loops variable there is restriction on 5 runs. So how there can be 25 times per second? And if this mean, that user input catch inside updateGameState also 25 times\sec?
